Segmental accumulative jacking installation method of vase-shaped space steel structure

Abstract

The invention discloses a sectional-stacking jacking mounting method of a vase-shaped space steel structure. The method comprises the following steps of: dividing construction sections and adjustment sections according to the abrupt change positions of the cross section of the vase-shaped space steel structure; specifying the initial shrinkage abrupt change position to the elevation of a jacking construction platform according to the bottom-to-top cross section dimension of the vase-shaped space steel structure; mounting the construction sections under the elevation of the jacking construction platform; erecting a jacking construction platform supporting system, an reinforcement region and a surrounding-protecting bracket, and mounting the jacking construction platform; mounting a jackingdevice on the jacking construction platform; employing a synchronous control system to perform control, jacking one by one and mounting by stacking a plurality of construction sections above the elevation of the jacking construction platform by means of a jacking device; and in the mounting process, when every construction section is jacked, mounting one adjustment section between the jacked construction section and the construction section to be jacked until the whole vase-shaped space steel structure is mounted and formed. No other large-scale assistant hoisting appliance is needed to be mounted, so that the work amount and difficulty of construction assistant measures are reduced, the construction safety is guaranteed and the cost is saved.

Description

technical field [0001] The invention relates to a method of segmented accumulative jacking and installation of a vase-shaped space steel structure, in particular to a construction method for segmental accumulative jacking and installation of a vase-shaped space steel structure using synchronous control technology. It belongs to the technical field of civil engineering construction. Background technique [0002] With the continuous development of my country's economic construction and the ever-changing design ideas and methods, some steel structures with peculiar architectural shapes have been designed. The main building of the Buddha Tooth Relic Hall in Wenshang, Shandong Province is one of many new steel structure systems. , How to choose the vase-shaped steel structure with large variation in cross-section size and high installation height has been a technical problem that has been puzzling construction technicians. [0003] There are many types of steel structures that va...

Problems solved by technology

However, when the cross-sectional size of the vase-shaped space steel structure along the height direction changes greatly, it is necessary to adjust the position of the jacking point and the jacking equipment several times during the jacking process, which will inevitably result in doubling the supporting materials and labor at the lower part of the construction platform. increase, resulting in an increase in the cost of the construction measures for the floor or ground reinforcement supporting the supporting material and the extension of the construction period
